Specification of Letters Patent.

Patented Nov.i26, 1907.

Application filed July 27. 1905- Serial No. 271.407.

To all whom it may concern:

Be it known that ARTHUR BUGKLER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, has invented certain new and useful Improvements inLoom-Shuttles, of which the following is a specification.

The object of this invention is to provide a loom shuttle with a simpleand el'ticient bobbin or cop holding device movable into and from thebobbin receiving chamber of the shuttle and having provision whereby thebobbin after being applied to the device is firmly secured thereto uponthe latter being moved into the chamber, and whereby the bobbin isreleased to permit its removal from the device upon the latter beingmoved out of the chamber.

The invention consists in the novel con-- struction and combinations 'ofparts hereinafter fully described and claimed.

In the drawings: Figure 1 is a plan view of a shuttle embodying myinvention. Fig. 2 is an enlarged sectional view, as on the line 2-2 ofFig. 1. Fig. 3 is a similar sectional view, showing the parts in adifferent position. Fig. 4 is a sectional view, as on line 33, of Fig.2. Fig. 5 is a sectional detail, as on the line 5-5 of Fig. 2. Fig. 6 isa view of the spindle detached.

1 designates the body of the shuttle which is of usual and well knownconstruction, the same being provided with the bobbinreceiving chamber3. Formed in the body of the shuttle and opening into one end of the,chamber is a recess 4. Extending through the recess l is a pin 6 uponwhich is mounted the basal end of a hollow tapering spindle 7 adapted toreceive a cop or bobbin. The free end of the spindle 7 extends into thechamber 3, as shown in Figs. 1 and. 2, and it is adapted to be swungupon the pin 6 to the position shown in Fig. 3, for the purpose ofapplying a bobbin thereto or removing a bobbin therefrom. The basal orpivoted end of the spindle is made square in cross section, as shown,and bearing against the bottom of said end is a flat spring 8 which ismounted on pins 9 and 10 extending through. the recess 1. The tendencyof the spring 8 is to maintain the spindle 7 in the position shown inFig. 2 against a stop pin 11, and also to maintain the spindle 7 in theposition shown in Fig. 3 against a stop pin 12. Thus it will be seenthat the spindle may be moved into or from the chamber 3 and that saidspindle is maintained in either position by the action of the spring 8.

The tapering spindle 7-is made in two parts and the long taperingportion of each part projecting from the squared basal end is madesubstantially semicircular in cross section, as shown in Fig. 5, and thetwo adj acent ends of saidparts forming the basal end of the spindle aresecured together by soldering or otherwise, leaving the free ends of thelong tapering portions of the parts free to move from and toward eachother, due to the springiness of the metal forming the spindle.

Extending through the spindle 7 is a pin 13 one end 14. of which is bentand extends at right angles to the axis of the spindle and out throughan opening 15 and between the pin 11 and the spring 8. The other end 16of the pin 13 is made tapering and extends into the free end of thespindle. When the pin 13 is moved toward the free end of the spindle,the free ends of the two parts forming the spindle are forced apart, andwhen the pin 13 is moved toward the basal end of the spindle, the freeends of said parts are permitted to spring together. Thus the free endof the spindle may be expanded and contracted by operating the pin 13.

WVhen the parts occupy the position shown in Fig. 3, a cop or bobbin maybe readily ap plied to the spindle, and by then moving the parts to theposition shown in Fig. 2, to move the bobbin into the chamber 3, the end14 of the pin 13 takes against the spring 8 which forces the pin 13toward the free end of the spindle, thereby expanding said end andbinding the bobbin to prevent its removal from the spindle. WVhen theparts are moved from the position shown in Fig. 2 to the position shownin Fig. 3, the end of the pin 13 takes against the pin 11 and withdrawsthe pin 13 from the free end of the spindle thereby permitting the twoparts of said end to move together to permit the bobbin to be removedfrom the spindle and the substitution of another one therefor.

The cops or bobbins placed upon the spindle 7 usually comprise a body ofthread wound upon a paper tube, and the expanding of the free end of thespindle after the bobbin has been placed thereon not only expands theend of the bobbin tube but also the end of the body of the thread thusserving to ellectually retain the tube upon the spindle and the body ofthe thread upon the tube, it being understood that the expanded end ofthe bobbin prevents its movement toward the free end of the bobbin andthe tapering spindle prevents the movement of the bobbin in the reversedirection during the motion of the shuttle.

I claim 1. The combination of a shuttle body provided with abobbin-receiving chamber, a spindle therein having an expansible freeend and adapted to receive a bobbin, and means for expanding the freeend of the spindle to engage and bind the bobbin.

2. The combination of a shuttle body provided with a bobbin-receivingchamber, a spindle having an expansible free end and movable into andfrom the chamber and adapted to receive a bobbin, and means forexpanding the free end of the spindle upon the latter being moved intothe ch amber.

3. The combination of a shuttle body provided with a bobbin-receivingchamber, a spindle supported at one of its ends and movable into andfrom the chamber and adapted to receive a bobbin, said spindle ineludingtwo parts connected near the supporting end of the spindle and havingtheir free ends movable toward and from each other, and a tapering pinlocated between said parts and adapted when the spindle is moved intothe chamber to engage said parts to move said ends from each other toengage and bind the bobbin.

4. The combination of a shuttle body pro vided with a bobbin receivingchamber, a bobbin-receiving spindle therein supported at one of its endsand including two parts connected near the supporting end of the spindleand having their free ends movable toward and from each other, and a pinlocated between said parts and having a tapering portion adapted toengage and move said ends from each 'other to engage and bind thebobbin.

In testimony whereof I affix my signature in presence of two witnesses.
